Other object types seem to work.
How could that NSNumber be initialized? It could only be via -init. A quick test here shows that [[NSNumber alloc] init] returns nil. I.e. it fails, because that's a nonsensical thing to do. So is putting an NSNumber in a NIB. What in the world are you trying to do? In general, it makes no sense to put things other than views or controller objects into NIBs. NSNumbers are value objects, suitable for the model layer of your app. Regards, Ken _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
